HARDWARE OVERVIEWThe CyberSWITCH is an embedded communications platform. It uses a flash file system (insteadof a hard disk) and a two-stage boot device to initialize the platform and download systemsoftware. System software is preconfigured to allow immediate connection via a Local AreaNetwork (LAN) or Wide Area Network (WAN) with Telnet and/or TFTP access. The software canalso be accessed via the RS232 port on the system, and a terminal-emulation software package.The CyberSWITCH offers flexibility. With its internetworking capabilities, you may use it as astand-alone device to service small businesses. Or, you may use it as a router with a larger “hub,”fielding data packets and forwarding them.The CyberSWITCH works with a mix of bridges, routers, hosts, PCs, and workstations. Thesecombinations provide internetworking capabilities that will allow LAN-to-LAN applications suchas telecommuting, electronic mail, multi-media transmission, imaging, and CAD.This chapter includes safety considerations and a description of Workgroup CyberSWITCHplatforms and modules.S AFETY C ONSIDERATIONSThe CyberSWITCH contains a lithium battery to support its time-keeping functions. It is a long-lasting battery, and was not intended to be user-replaceable.
